Comet 17P/Holmes Changes in November-December 2007

This set of images shows the development of Comet 17P/Holmes
over a few weeks in November-December 2007 (the full-moon
weekend of Nov. 24-25 was skipped).

While the nature of
the film media and digital post-processing preclude serious
measurements, the expansion of the
central dust coma, weakening of the fluorescent gas shell,
and disconnection and disappearance of the blue ion tail
are apparent.
